Basic Right Triangles

Right Triangle: A triangle with a right angle (90 degrees)
When finding sides and angles in basic right triangles, variables like "x" and "y" are used with opposite angles. To find angles and sides in a right triangle, it is important to remember SOH CAH TOA.
Sin = opposite/ hypotenuse       Cosine = Adjacent/ Hypotenuse      Tangent= opposite/ adjacent
 Also remember for right triangles a^2  + b^2 = c^2
